SharpLink has formally opposed Ethereum Improvement Proposal (EIP) 8363, calling it "the wrong proposal at the wrong time." The digital asset firm, which operates an Ethereum staking infrastructure business and is publicly traded on Nasdaq under the ticker SBET, warned that the draft could weaken Ethereum's decentralized finance (DeFi) ecosystem, staking returns, institutional demand, and network security.

Chief Executive Joseph Chalom outlined four reasons for the company's opposition in a post on X:

EIP-8363 and Its Potential Impact on DeFi

SharpLink's first objection centered on Ethereum's DeFi sector. The firm said staking yield serves as a base rate for on-chain markets after accounting for costs and inflation. Since Ethereum transitioned to proof-of-stake consensus via the Merge upgrade in September 2022, staking rewards have become central to the network's economic model. Staking tokens currently have a total value locked (TVL) of approximately $35 billion and are widely used as collateral across various lending systems.

The company argued that operating costs, liquidity costs, and slashing risks can push actual returns close to zero or even below that threshold. Lower interest rates could trigger collateral withdrawals from the Ethereum network, making lending markets thinner and reducing credit availability within DeFi. Stakers and medium-sized entities would be the most directly affected.

EIP-8363, known as Tapered Issuance Burn, is a draft proposal that would alter Ethereum's existing staking reward system. Under the proposal, an increasing share of validators' rewards from attestations, block proposals, and sync-committees would be burned as more ETH gets staked. The burn would reach 100% once approximately 60.25 million ETH—half of all issued ETH—has been staked. At that point, the issuance yield would drop to 0%, and validators would rely solely on tips and MEV (maximal extractable value) rather than issuance rewards. Ethereum currently has well under half of its total supply staked, though the staked proportion has grown steadily since the Merge.

Institutional Demand and Network Security Concerns

SharpLink's second objection addressed institutional demand for ETH. The firm argued that ETH's native yield gives holders an edge over other digital assets. The company pointed to growing institutional exposure through exchange-traded products, digital asset trusts, and private funds. U.S. spot ETH ETFs launched in mid-2024, adding a regulated avenue for institutional exposure.

The third point emphasized that Ethereum's internal finance mechanism helps cover the costs of securing the network, operating nodes, maintaining client software, and reinvesting in system infrastructure. Reducing rewards, SharpLink warned, could halt capital inflows entirely and encourage institutions to sell their ETH after unstaking.

The company also raised concerns about the proposal's timing, citing accelerating institutional activity in the Ethereum ecosystem. Robinhood is developing a Layer-2 chain, BlackRock has launched tokens representing a money-market fund on Ethereum, and BNY and Galaxy Digital have launched a staking alliance. SharpLink argued that EIP-8363 has arrived just as these institutional developments are gaining momentum.

Stani Kulechov Echoes Concerns

Aave founder and CEO Stani Kulechov has also raised concerns about related issuance plans. He warned that zero rewards above a 50% staking ratio could make returns unpredictable or uneconomical, potentially reducing participation and weakening the network. Aave is one of Ethereum's largest DeFi lending protocols, making Kulechov's assessment particularly relevant to the lending-market dynamics SharpLink described.

Unfortunately this proposal doesn't achieve the outcome it tries to achieve and is actually hurtful for Ethereum. It caps Ethereum staking rewards to 0% when over 50% of supply staked. What this mean is that Ethereum staking yield becomes unpredictable and even fully… — Stani (@StaniKulechov) August 4, 2026

Kulechov later described SharpLink as one of the supporters and funders of the Ethereum ecosystem.

Despite the opposition, EIP-8363 remains in a draft state and has neither been accepted nor scheduled for an Ethereum upgrade. Ethereum's improvement proposal process requires broad community consensus across developers, validators, and researchers for any change to advance from draft toward implementation, and many draft proposals are revised significantly or never adopted.
